FICA: the tax that funds Social Security and Medicare

FICA payroll tax is split into two parts. Social Security tax is 6.2% on wages up to an annual wage base ($184,500 for 2026) β€” earnings above that threshold are not subject to the Social Security portion at all, which is why very high earners see a smaller effective payroll tax rate on their full income. Medicare tax is 1.45% with no wage cap, plus an additional 0.9% Medicare surtax on wages above $200,000 for single filers ($250,000 married filing jointly), which employers do not match.

Employers pay a matching 6.2% and 1.45% on top of what is withheld from an employee's paycheck, so the true cost of FICA to the economy is double the 7.65% employee-side figure most people see on a pay stub. Self-employed workers pay both halves themselves through self-employment tax, which is why that rate is roughly double the employee rate.

Frequently asked questions

Is FICA the same as federal income tax?

No β€” they are separate. FICA specifically funds Social Security and Medicare and is a flat percentage (subject to the Social Security wage cap), while federal income tax is progressive and funds general government spending.

What happens once I earn above the Social Security wage base?

The 6.2% Social Security portion stops applying to any further wages that year β€” only the 1.45% Medicare portion (and the 0.9% surtax above the relevant threshold) continues on income above the cap.

Do employers pay FICA too?

Yes, employers match the employee's 6.2% Social Security and 1.45% Medicare contributions, effectively doubling the total FICA tax paid on each dollar of wages, split between employer and employee on the pay stub.

Does FICA fund my personal retirement account?

No. Unlike a 401(k), FICA contributions do not sit in a personal account β€” they fund current Social Security and Medicare benefits on a pay-as-you-go basis, and your own future benefit is calculated from your earnings record, not a balance you accumulate.
